    Hi! (sorry for replying so late)

    I had a similar problem when I tried, and it turned out that for one of the letters instead of replacing the coded sections with that letter I had replaced the spaces with that coded section.

    It might be something different though.

    Hope you manage to solve it!

    @The_Bombe I think you have made a mistake on splitting it in set of 6 but you are on the right track!

    @The_Bombe
    Do you have a whole number of characters to decode?

    For those having trouble with the back slashes in 9B when using Python, try raw strings. A raw string is a string preceded by the letter r:

    x = "1\t23"
    print(x)    # Prints   1    23
    
    y = r"1\t23"
    print(y)    # Prints   1\t23

    Python ignores escape sequences, such as \n or \t, in raw strings, treating them as normal characters or text.

    I think 9B is most likely to be a Slash and Pipe Cipher but there is no spaces in between letters so I don’t know where to start?Maybe try ‘MYDEAR’?

    if you look at it in terms of ratios, 2156:2156:8624 can be simplified to 1:1:4. adding the 2 ones to the 4 can result in 6 so you may want to try grouping the cipher into groups of 6

    If anyone is using python to help decrypt 9B, I will say this:
    you might want to research what python thinks when it encounters a double slash.

    For anyone else:
    the variant of the telegraph is not mentioned in the Wikipedia page, but have you considered the previous key lengths?

    Hopefully this hint is allowed, and good luck!

    The Cooke and Wheatstone five-needle telegraph suffers the defect of only being capable of expressing 20 unique characters. By having one additional needle may help with solving the problem!

    No I’ve just realised I was completely wrong about the Trifid cipher, sorry if it misled anyone!

    It wasn’t entirely misleading! Harry

    To get around the back slash problem in Python :
    In Word, replace all “|” with “A”, “/” with “B” and “\” with “C”.
    Feed the result to your program.

    For 9B, its actually so simple just look at case file 9.2 , then look at the character count for 9b and check factors of the number to create a diagram that works (hopefully this is allowed through) good luck!! Also for coders if you change the whole thing into letters eg aabca then that should work

    Our group has been having similar issues where parts are perfectly decoded however some parts are just gibberish we thought it might be an issue with our code but now I’m not sure? Perhaps there is a second step we are missing

    Only one step.

    I keep getting only chunks of text that are solved but random gibberish for the other sections

    Sorry to disturb anyone but does any one know how to write a code to separate blocks of characters/letters.
    Please can anyone help me.
